Abstract

An apparatus for delivering a tool into a nuclear reactor jet pump submerged in a reactor pool includes a frame, and a propulsion unit for controlling the movement of the tool delivery apparatus within a pool of liquid. A guide assembly provides for delivery and insertion of the tool into an inlet of the jet pump and includes a bore insertion portion. A tool position driver provides for controlling the vertical position of the tool in relation to the guide assembly.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is related to U.S. application Ser. No. ______, attorney docket no. 162006-1 filed on Apr. 12, 2005, coincidental with the filing of the present application.FIELD OF THE INVENTION

[0002] This invention relates generally to an apparatus for delivering a tool to a submerged bore, and more particularly to a assembly for delivering an inspection tool into a submerged nuclear reactor jet pump. BACKGROUND OF THE INVENTION

[0003] Bores such as pipes or cylindrically shaped equipment are often submerged in a pool of water or other liquid. There is often a need to have a maintenance tool or inspection probe delivered into the submerged bore. For example, a reactor pressure vessel (RPV) of a boiling water reactor (BWR) typically has submerged bores that need to be inspected during maintenance routines. Hollow tubular jet pumps having internal bores are positioned within an annulus to provide the required reactor core water flow. ...
